Abstract: Apparatus and method for changing one or several dimensions of a load space in a working machine, when the dimensions are width, height or length. In the method the weight of the load in the load space is determined or the weight of the load in a full load space is predicted on the basis of said determination and the current value of the dimension; a new value is calculated for the dimension by means of which it is possible to reach a set maximum quantity for the part of the weight of the load; and the dimension of the load space is adjusted either gradually or at once to a position according to the new value.

Abstract: The invention relates to a bus system comprising a bus line, to which electronic devices (26–36) can be connected. According to the invention, at least one electronic device (36) can be connected via a detachable interface (38) to the bus line, said interface (38) having a first connection (42) that is connected to a first section (12) of the bus line and a second connection (44) that is connected to a second section (14) of the bus line. To prevent an interruption of the bus line when the interface (38) is free, a bypass device (40) automatically creates a connection between the first section (12) of the bus line and the second section (14) of the bus line, if no electronic device (36) is connected to the interface (38).

Abstract: The invention concerns informatics equipment for an actor in a logistic chain of production or processing of products, more specifically of food products.

Abstract: A sprayer system includes one or more spray nozzle systems and a recirculation line which contains a Venturi for recirculation of non-sprayed liquid into a tank during breaks in spraying. To facilitate circulation, restrictors are placed in an upstream area of each nozzle system feeding line, and a downstream control valve is inserted between each nozzle system and the recirculation line. Each nozzle system can be independently controlled. Closing a control valve activates the spraying system associated with that valve, whereas opening the valve enables the liquid to circulate through the recirculation line into the tank to prevent unwanted dripping, demixing and depositing.

Abstract: An arrangement for the suspension of wheels of a working machine moving on a terrain, the arrangement comprising a pair of adjacent wheels arranged to support a frame part placed on a center line between the wheels; suspensions arranged between each wheel and the frame part to elevate and descend each wheel with respect to the frame part, wherein each suspension comprises a lower suspension arm and an upper suspension arm, which lower suspension arms are mounted by means of first joints to the frame part and by means of second joints to mounting arms, in which the wheels are mounted in a rotatable manner, and which upper suspension arms are fixed by means of third joints to the frame part and by means of fourth joints to the mounting arms, wherein, in each suspension, the first joint and/or the third joint is placed on said center line.

Abstract: A method for stabilizing an articulated vehicle, which articulated vehicle comprises at least a front frame structure and a rear frame structure, and a frame joint structure, which is arranged to couple the frame structures to each other and to allow them to rotate both in relation to each other, away from the normal position, as well as at the same time around an axis, which is substantially parallel to the longitudinal direction of the articulated vehicle. In the method a supporting force is maintained, which force affects between the frame structures and resists the rotation of the frame structures away from normal position, and the maximum of said supporting force is controlled in such a manner that it is dependent on the difference of rotations at least when said difference is increasing and at least when said difference is static.

Abstract: In accordance with the present invention, there is provided a tillage conservation plow (100) for plowing the earth and exposing, on the surface of the earth, weeds and past harvest residue. The plow includes a hitch frame (1) and a framework (2) connected to the hitch frame. A support (10) is connected to the framework. The support is operable to allow the earth to pass unturned. A blade (4) is connected to the moldboard support. The support, in combination with the blade, is operable to place the weeds and past harvest residue on the surface of the earth without turning over the soil.

Abstract: A conservation tillage implement including a shredder with a transverse rotor hood structure having one-piece end panels which are welded to each side of the hood and project rearwardly of the hood to receive a toolbar which extends the width of the implement. The center of the toolbar is connected to a pair of parallel upright central panels which are connected to the central rear portion of the hood. A reinforcing member extends from the central rear portion between the central panels around the top of the hood adjacent the hitch structure which connects the implement to a tractor. The end and central panels and reinforced hood structure define a compact, unobtrusive frame which is sturdy enough to pull heavy drawbar loads and resist heavy torque loading. In one embodiment of the invention, the toolbar supports a plurality of transversely adjustable deep tillage tools such as rippers, and disk structure is connected by adjustable bracket structure to the toolbar behind the rippers.

Abstract: A rotary internal combustion engine includes a rotor with apex seals installed in slots which extend axially through apexes of the rotor. Each slot has stepped side walls which define an inner narrower slot portion and an outer wider slot portion. The portion are joined by a pair of outwardly facing ledges on both sides of the slot. Each apex seal has a outer head which includes a pair of overhanging or cantilevered lips. The width of the overhang is slightly larger than the width of the ledges so that seal-slot contact is made near the outer seal tip.
